Audi miss fire

\015 I have a 2003 a4 1.8 turbo, it idles rough, and has a lose of power. \302\240Can't even reach 80km/h. \302\240 Coil packs are fine, spark plugs are fine, also checked the injectors. hooked it up to a code reader and said 3 out of my 4 cylinders are miss firing. \302\240Wondering if the timing would have any thing to do with that. \302\240 any other suggestions would be great.\015 Posted / edited by AnonymousUser on : 14-10-2019

Answers :

You have the cam and crank sensors to check. also driving like this can ruin the cat so that should be checked as well. and the o2's. the cam and crank sensors can be checked on a scanner or scope or check there resistance if you have what the resistance values should be. there are other things that can cause this a fuel filter clogged up to many things but check the cam , crank sensors and items like fuel filter ect plus cat and o2's they should be swithcing when repair is done above and below 500 rich to lean lean to rich. make sure they are not stuck.
